基于不同交通方式的上海浦东新区公园可达性分析

城市公园作为现代城市的重要组成部分,其可达性是影响人们有效利用公园以及衡量城市公园布局合理性的重要因素。本文通过采集实时在线地图交通数据,针对步行、公共交通和自驾车3种不同交通方式下上海市浦东新区所有公园的可达性进行分析研究,以期为城市管理和规划提供科学参考和依据。研究表明:浦东新区北部内环内的区域,有数量众多的小型公园,步行方式下公园的可达性达到了较好水平,而中部和南部区域因为公园数量少,只有少量围绕在公园附近的居民小区可达性较好,其他受距离限制,步行前往公园的可达性较差;自驾车主要受到路况影响,早上的可达性优于中午与晚上;公共交通前往公园的可达性除了受道路拥堵情况的影响,还受限于运营时间,傍晚的可达性略好于早上,早上的可达性略好于中午。从空间分布看,内环区域可达性好于外环区域:靠近市中心的区域公园密集、公共交通网密集,公园可达性高;中部与北部区域公园少、公共交通网络稀疏,可达性低。

Accessibility analysis of parks in Pudong New Area based on different transportations

Parks play an important role in the metropolis.The accessibility of parks is an important factor to evaluate the rationality of parks layout as well the availability of parks.In this paper,we studied the accessibility of all parks from residential area in Pudong New Area,Shanghai by walking,public transport and self-driving,respectively,based on the dynamic real-time online map traffic data.The results show that the accessibility of parks reached a high level by walking in the northern of Pudong New Area inner race because there are a large number of small parks within this area.The secondary accessibility of parks is in the central and southern areas,where only small number of residential areas around the parks that has better accessibility.Limited by distance,the accessibility of parks in other areas of Pudong New Area is poor.The accessibility of parks by self-driving in the morning is better than that in the noon and evening.In addition,being affected by road congestion,the accessibility of parks by public transport is influenced by the operation time,the accessibility in the evening is the best,the second is in the morning and the worst is in the noon.In terms of spatial distribution,the accessibility of parks in the inner race region is better than that of the outer race.The reason maybe that the parks closed to the city center are dense with the better network of communication facilities while there are fewer parks in the central and northern regions,the public transport network is sparse,and accordingly the accessibility of parks is lower.
